Cathedral Stone Product line consists of materials and tools that make the “invisible” masonry repair possible, as these preservation professionals learned on-site.

CSP supports the effort by training cemetery preservation interns and staff at no charge. In exchange, Green-Wood allows CSP to use its maintenance garage for our demonstrations, which CSP offers to engineers, architects, preservationists, and others.

CSP representatives recently spoke on the evolution of mortar for a group of stonecutting interns at Eastern State Penitentiary Historic Site in Philadelphia, which was in operation from 1829 until 1971. The prison was abandoned for 20 years and is now a major preservation project.

I called around and soon learned that the laborers had gone on strike. Well, it was no wonder that the cathedral was a ghost town. Without laborers, you can’t get anything done. You can’t mix cement. You can’t make mortar for setting stone. You can’t build a cathedral. Nothing gets done without labor.

This grout is engineered to secure helical ties and anchors in masonry.

Cathedral Stone Products is now solely in a position to manufacture and distribute the complete line of Jahn Masonry Restoration products worldwide.

The conference was held at the Newport Art Museum which, with its original stick-style Victorian structure and complementary expansions, was the perfect backdrop for a bunch of restoration professionals to gather.
